Lipidomic analysis of cardiac triacylglycerol (TG), diacylglycerol (DG), and ceramide in Hsp72 Tg mice fed a NC or HFD. Mice were fed a NC or HFD for 12 weeks from 8 weeks of age. a Total TG levels and b individual cardiac TG molecular lipid species. c Total DG levels and d individual cardiac DG molecular lipid species. e Total ceramide levels and f individual cardiac ceramide molecular lipid species. n = 5–9 per group. *p < 0.05, **p < 0.01 for dietary effect; ^† p < 0.05 for genotype effect. All data are presented as mean ± SEM
